Digital image processing apparatus and method of controlling the same

摘要

A digital image processing apparatus and a method of controlling the same. When the composition of a subject displayed on a display of the apparatus is changed during application of a first shutter-release signal, a current auto-focus (AF) region moves along with the subject and displayed on the display at the same time as the subject. The apparatus can further display an initial AF region on the display in a manner distinguishable from the current AF region. After the composition of the subject is changed, while the current AF region moving along with the subject is being displayed on the display, when the application of the first shutter-release signal is interrupted, an AF region is reset as the initial AF region. Also, an image file can be generated and stored after application of a second-shutter release signal which occurs after application of the first shutter-release signal.

主权项

1. A digital image processing apparatus comprising:
an image receiving unit that obtains an image of a subject; a display unit; and a processing unit configured to:
display an auto-focus (AF) region on the display unit in a position as an initial AF region;adjust a focus corresponding to the subject at the current AF region upon receiving an auto-focus lock signal;control the current AF region to track the subject when the subject is in motion while the auto-focus lock signal is applied;display the current AF region tracking the subject on the display unit; andwhile the current AF region tracking the subject is displayed on the display unit, when a state of the auto-focus lock signal is changed, reset a position of the current AF region tracking the subject as the initial AF region.
